Bitcoin
This is the network the latest block page reads. It started in 2009.
The 2008 paper is titled “Bitcoin: A Peer-to-Peer Electronic Cash System”. It was published under the name Satoshi Nakamoto. That paper put the parts of a blockchain together for this use.
Bitcoin is not a stablecoin. Computer code issues it, on a network that no one person or company controls. The price tends to move up and down quickly, because other assets do not back it. That is one reason crypto is not widely used to pay for things.
